AND THOMAS BRAMWEL IMPROVEMENT IN SAWlNG-MACHINES.

Specication forming part of Letters Patent No. 178,168, dated May 30, 1876; application filed April 22, 1876.

To all whom it mayconcem:

Beit known that I, GEORGE LEE, of Belleville, in the county of' Dane and State of Wiscousin, have invented a new and valuable Improvement in Sawing-Machines; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, making a part of this specification, and to the letters and figures of' reference marked thereon. v

Figure l ofthe drawings is a representation of a side elevation of my drag-saw attachment.

This invention has relation to drag or crosscut saws which are operated by Wind-wheels5 and the nature of my invention consist-s in a novel arrangement of levers in combination with a crosscut-sawland a vertically-movable rod, whereby endwise motion is communicated to the saw by the rotation of 'the wind-wheel, as will be hereinafter explained.

In the annexed drawings', A designates the 4pillar of a wind-wheel, which is, preferably,

constructed of triangular form, with a vertical central standard, a, in the center of it. At the upper end of the standard a is a short shaft, b, which is cranked on both ends. One

crank is suitably connected to the wind-wheel shaft, and the other crank is pivot-ed to the upper end of a rod, C, which extends down one side of the post or standard a, and is suitably guided and allowed free vertical motion. D designates a lever, which is pivoted at one end to the pillar A, and at the other end is connected by a link, c, to an angular lever, E, which is also pivoted to the pillar A. The

lever D is pivoted at or near the middle of itsA length to rod C, and the latter is free to vibrate and accommodate itsell to the movements of the said lever D,.so that there will be no binding of the parts during the operation of the mill. The right-angular lever E is strengthened by means of a brace, f, and the' lower longest arm of this lever is pivoted to one end of a pitman-rod, G, the opposite end of which rod has pivoted to ita saw, S, that is free to rise and descend.
